To all whom it may concern:

Be it known that I, LUIS It. Acos'rrnr, a citizen of the Republic ofVenezuela, residing at Caracas, in the Federal District and Republic ofVenezuela, have invented certain new and useful Improvements in l/Vave-Motors, of which the following is a specification.

My invention relates to new and useful improvements in machines whichare ordinarily termed wave motors, and are employed to convert themotion of the waves or tides into available force or power to drivedifferent machinery.

An important object of this invention is to provide a machine of theabove mentioned character, which utilizes in its operation the forces ofpotential energy of an elevated weight and the movement of waves ortides to return the weight to its elevated position after its descent.

A further object of the invention is to provide novel means to convertreciprocatory motion into a continuous rotary motion.

A further object of the invention is to provide a machine of the abovementioned character, which is positive and reliable in operation andcapable of developing high power.

A further object of the invention is to provide a wave motor which issimple in construction, cheap to manufacture, strong, and durable.

Other objects and advantages of the in vention will be apparent duringthe course of the following description.

In the accompanying drawings forming a part of this specification and inwhich like numerals are employed to designate like parts throughout thesame, Figure 1 is a plan view of the entire machine, Fig. 2 is a sideview of the mechanism for converting reciprocatory motion into rotarymotion, Fig. 3 is a detail sectional view through the reciprocatoryelement of the mechanism, Fig. at is a side view of the entire machinetaken at a right angle to Fig. 2, and, Fig. 5 is a side view of aslightly modified form of the invention.

In the drawings, wherein for the purpose of illustration, I have shown apreferred embodiment of my invention, the numeral 6 designates anupstanding post or support, which is planted upon the shore and upon theupper end of which is mounted a braclze 1 or bearing 7, receiving agrooved pulley S.

Disposed about this grooved pulley is a steel Specification of lettersPatent.

cable 9 or other flexible element extending downwardly to be attached toa movable float 9. This float may be in the form of a ship, raft or anysimilar structure, but is preferably in the form of a ship with acompletely closed deck, which may be provided with a suitable number ofhermetically sealed hatchways. The float 9 is connected to anchor chains16, which are attached to fixed anchors, weights, or piles 11. It isthus seen that the chains 10 retain the float 9 in proximity to thepiles or anchors 11 but allow of the free approximately horizontalreciprocatory movement of the float in a longitudinal direction. Theanchor chains restrict thevertical movement of the float by the waves,said float moving longitudinally in the arc of a circle.

The cable 9 is attached to an upstanding cylinder 10, which is arrangedcentrally of the float or ship 9. This cylinder starts from the bottomof the ship and terminates i ment of the cylinder 10, hereinabove de-'scribed. This second float is held against undue movements by anchorchains 14, which are attached at their lower ends to anchors, weights,or piles 15. Use is thus made of the movement of the two floats, whichis ordinarily simultaneous in opposite directions.

I have found that satisfactory results may be obtained by having thefloat l3 relatively stationary. I have also found that the horizontalmovement of the float 9 is greatly increased when this second stationaryfloat 13 is employed.

The numerals 16 and 17 designate pairs of upstanding supports or postsdisposed near the post 6 and upon the upper ends' of which are mountedbearings 18, to receive horizontal rotatable shafts 19. Rigidly mountedupon the shafts 19 are pulleys 20, engaged by a common belt 21, whichextends upwardly and engages flywheel pulley 22. The pulley 22 isrigidly mounted upon a power distributing shaft 23, journaled throughbearings 24, which are attached to the upper ends of upstanding supportsor posts 25. Connected with the shaft 23 is a pulley 25 which is gearedor connected in any suitable manner with the machinery or devices to bedriven. Any other suitable means may be employed for this purpose.Rigidly connected with corresponding ends of the shafts 19 are outerpinions 26, which engage pairs of inner pinions 27, as more clearlyshown in Fig. 2. These pairs of inner pinions are mounted upon stubshafts 28, journaled through bearings 29, which are fixed uponupstanding supports or posts 30, as shown.

The numeral 31 designates an upstanding guide, which fits within alongitudinal central opening 23, formed in the sides of a reciprocatoryweight 33. The cable 9 has its free end forked, as shown, and connectedwith the upper end of the reciprocatory weight 33, by eye bolts 3a orthe like. I have found that the best results are obtainable by havingthe weight 33 about onehalf as heavy as the movable float or floats.

The reciprocatory weight 33 carries racks or sets of swinging pawls,finger, or elements 35 and 36, pivotally connected therewith by means ofpins or stub shafts 37 (see more particularly Fig. 3). The innerenlarged ends 38 and 39 of the pawls 36 and 37, respectively, operatewithin recesses or pockets 4:0 and 41, as shown. The pockets 10 havelower horizontal shoulders 42 while the pockets ll have upper horizontalshoulders 13. The sets of pawls 35 are free to swing downwardly onlywith relation to the reciprocatory weight 33 and the set of pawls 36 isfree to swing upwardly only with relation to said weight. Leaf-springs14E of suitable stiffness are attached to the weight 33 and engage pins38 carried by the inner enlarged ends 38 and 39 of the pawls and serveto normally retain such enlarged ends in engagement with the horizontalshoulders 42 and 43, thus returning the pawls to their normal positions.The sets of pawls 35 and 36 engage the pairs of inner pinions 27, whichare disposed upon opposite sides of the reciprocatory weight 33. Themechanism to convert the reciprocatory motion into rotary moton ismounted upon the shore a suitable distance from the movable float orfloats. The steel cable may be formed in two parts to be detached whenit is desired to stop the operation of the machine.

The operation of the machine is as follows :The float or floats arenormally retained in their starting position by the weight 33 andreturned thereto by the weight when moved therefrom. When the float ismoved forwardly by the wave in the direction of the arrow, the cable 9is pulled to elevate the reciprocatory weight 33. The sets of pawls 36now turn the left hand pair of inner pinions 27, which in turn rotatethe left hand pinion 26. This rotation is imparted to the pulley 20 andthrough the medium of the belt 21 to the pulley 22. Upon this upwardmovement of the weight 33, the other set of pawls 35 do not turn theright hand pinions 27 but trip over the same. When the float 9 moveslongitudinally in a reverse direction, the weight 33 descends, returningthe float to its starting position. The set of pawls 35 now turns theright hand inner pair of pinions 27 while the other set of pawls 36 donot turn the left hand pair of pinions 27 but trip over the same.

It is to be understood that the form of my invention herewith shown anddescribed is to be taken as a preferred example of the same and thatcertain changes in the shape, size, and arrangement of parts may beresorted to without departing from the spirit of the invention or thescope of the subjoined claims.

Having thus described my invention, I claim 1. In a machine of thecharacter described, a plurality of spaced movable floats, anchor meansfor the floats so that the same will move away from each other whenelevated by the waves, a flexible element con-l nected with the floatsto be pulled by the combined movements of the floats, and mechanismoperated by the flexible element.
